Not likely. It's much more likely that the price will go up to help pay for passports for poor people who can't afford to pay for their own.
This would make the border problem easier to identify. If you're within 100 miles of the border and you don't have a passport or other proof of US citizenship, you get detained.

No way!
I live within 100 miles of the border and that would mean I would have to carry a passport anytime I left the house!
